Remove the -cxx-abi command-line flag. This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

When doing a derived-to-base class through a virtual class, we don't have to get the vbase offset from the vtable if the derived class is marked final. llvm-svn: 124523 2011-01-29 11:18:56 +08:00

Account for calling convention specifiers in function definitions in IR test cases Several tests wouldn't pass when executed on an armv7a_pc_linux triple due to the non-default arm_aapcs calling convention produced on the function definitions in the IR output. Account for this with the application of a little regex. Patch by Ying Yi. llvm-svn: 240971 2015-06-30 01:29:50 +08:00			`// CHECK-LABEL: define {{.}}dereferenceable({{[0-9]+}}) %struct.B @_Z1fR1D`
